“…We found that mainly individuals aged 26-30, females, of Black or Black British or Arab ethnicity, or those with a Bachelor's degree completed the survey with the target incentive. While studies suggest that the decoy effect emerges at a young age and that testosterone is associated with inconsistent decisions [39,40], our study does not indicate that male participants were more likely to react to the decoy. Our study presents limitations that warrant further investigation.…”

This study introduces a new randomized field experiment exploring the impact of offering a decoy charity donation incentive together with a monetary reward to increase response rates in an online survey about coronavirus fears. The study used a two-stage approach, starting with a preliminary survey to investigate participant attitudes toward different types of donations. Subsequently, an experiment was conducted wherein a less desirable £2 donation (the decoy) was introduced as an alternative to a £2 Amazon voucher (the target) within the choice set. The study sample consisted of 431 university students. They were split into three groups: a control group with a standard £2 Amazon voucher incentive (216 participants), a decoy group with the target shown first (108 participants), and a decoy group with the decoy shown first (107 participants). We found significantly higher survey completion rates in the decoy than in the control condition (82.3% vs. 74.5%). Notably, an order effect was observed–presenting the target before the decoy led to a higher completion rate (89.8%) compared to presenting the decoy first (74.8%). Importantly, the inclusion of the decoy incentive did not introduce any response bias. This study offers a proof of principle that incorporating a decoy charity donation incentive into the choice set can have a positive impact on survey participation without adversely affecting response behaviour. It demonstrates the potential of such incentives to encourage participants to complete online surveys, even when a small monetary reward is offered.

“…Over the past decade, several studies have shed light on the relationships between circulating testosterone and consumer choice (Stanton, 2017). For example, testosterone administration has been shown to increase the decoy effect (Liao et al, 2018). Additionally, testosterone is associated with status-related consumption.…”

In line with recent research suggesting that testosterone may only be related to decisions under specific conditions, we show that testosterone is associated with conspicuous consumption only when intrasexual competition is high. In three studies, we provide empirical evidence that prenatal and circulating testosterone are only related to conspicuous consumption when intrasexual competition is high. These findings are in line with recent literature that posits that testosterone is only related to particular decisions or behavior when status is at stake. In Study 1, we find that masculinized digit ratios (an indicator of high prenatal testosterone exposure) are only related to greater conspicuous consumption preferences for men that score high on an intrasexual competitiveness trait measure. In Study 2, we find that masculinized digit ratios are associated with greater conspicuous consumption preferences, but only among men who are primed with an intrasexual competition recall task.Finally, the purpose of Study 3 was to test if similar effects held when measuring circulating testosterone. We show that baseline levels of circulating testosterone are associated with greater conspicuous consumption preferences, but only after men are primed with intrasexual competition. Overall, we identify intrasexual competition as a crucial precondition for relationships between testosterone (prenatal and circulating) and conspicuous consumption to emerge. We argue that men with masculinized digit ratios and men with high circulating testosterone may be more likely to choose conspicuous products as a status-signaling strategy in the mating market if they are inherently intrasexually competitive or when they encounter an intrasexually competitive situation.
